TSD Q8
Two
boats, traveling at 5 and 10 kms
per hour, head directly each other. They begin at a distance of 20 kms
from each other. How far apart are they (in kms)
one minute before they collide.
(a) 1/12
(b) 1/6
(c) 1/4
(d) 1/2
The relative speed is 15 km/hr = 15 km/60 min = 0.25 km/min = 250 m/min.
Therefore, one minute before they collide, they are at a distance of 250mWrite Here
